Parameters identification of the asynchronous machine substituting circuit
Běloušek, Radim ; Cipín, Radoslav (referee) ; Patočka, Miroslav (advisor)
Mathematical model and substituting circuit both include several parameters, which is important to determine for a control. This work is target on identification of parameters of substitute circuit of the asynchronous machine in -network form. The work is divided into several main units. In the first of them are shown the methods of identification of asynchronous machine on the selected machine. The measuring of torque characteristic by classical way with dynamometer and by dynamically with fly-wheels is shown in the next part of this work. The final part of this work is devoted to interpretation and comparison of achieved results.

Algorithms for the Control of the Induction Motor
Hundák, Vladimír ; Běloušek, Radim (referee) ; Patočka, Miroslav (advisor)
Hlavným cieľom tejto práce je vytvorenie simulácií rôznych algoritmov riadenia asynchrónneho motora a vzájomné porovnanie ich vlastností. Zaoberá sa taktiež možnosťami konfigurácie náhradného zapojenia na T-článok, -článok a -článok. Obsahuje jednak teoretický rozbor, a taktiež aj simulácie jednotlivých spôsobov riadenia spolu s podrobným návodom na ich realizáciu. Celkovo budú vykonané 3 simulácie – simulácia vektorového riadenia s orientáciou na rotorový tok, vektorového riadenia s orientáciou na statorový tok a simulácia takzvaného prirodzeného riadenia. Ide o úplne nový typ riadenia, ktorého autorom je vedúci tejto diplomovej práce. Jeho simulácia bola vôbec prvým pokusom o funkčnú realizáciu tohto typu riadenia.

Parameter identification of the asynchronous machine substituting circuit
Otýpka, Jan ; Běloušek, Josef (referee) ; Patočka, Miroslav (advisor)
This work deals the precise identification of the substituting circuit parameters of the asynchronous machine for the gama-network, inverted Gama-network, T-network. I make use the best identification of the substituting circuit parameters of the asynchronous machine experimental method, theoretical procedurs and konstruction dates. In this work I solve various methods of identification and i compare solving like construction moment's characteristics from these establishen parametrs. Further I'm solving in my work comparations of two the costruction of them is similar with asyhronous mashins with power of 2,2kW , 2p = 2.

Substituting circuit of an induction machine
Běloušek, Radim ; Cipín, Radoslav (referee) ; Patočka, Miroslav (advisor)
Although induction motors are the simplest and most working reliability machines, is the identification of the parameters of their substituting circuit very difficult. There is solved the identification of the parameters of the substituting circuit in the T-network and ? –network in this work. The work also includes the proposal of magnetic circuit of the induction motor, the calculation of magnetizing and leakage inductances and resistances of the machine. The conclusion of the work is devoted to the sensitivity analysis of current and torque characteristics of induction motor upon the change of the single parameters of the substituting circuit.
